Granite high blocks for measuring part parallelism, usually supplied in pairs or threes.

Granite high blocks are used for measuring the parallelism of parts, typically supplied in sets of 2 or 3.

Characteristics and advantages of high blocks products such as granite:

No deformation, high hardness, excellent wear resistance

2. Abrasion-resistant, easy to maintain

3. Physically stable and tightly organized, the granite measuring platform features no chipping or burring on impact, maintaining its flatness accuracy. Its working surface is easy to maintain and preserve, with stable material properties that ensure long-term shape retention. It has a low coefficient of linear expansion, high mechanical accuracy, and is resistant to rust, magnetism, and insulation.
